Django + Apache + mod_wsgi fails when debug = false

Question

I'm trying to practise deploying a django application that is being developed. i've updated it to work with django 1.3, and everything works in debug mode. as soon as i switch DEBUG in settings to False, the server returns the fault below.

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Apache/2.2.14 (Ubuntu) Server at 192.168.1.220 Port 80

I personally don't want to be using apache, but it's being insisted upon me. anyone able to point me towards what it could be?

Make sure you have:

Created a 500.html template
Added your email address to the ADMINS setting so that you are emailed the traceback.
Look in the apache error logs to see if there is any useful information there. For Ubuntu, look in /var/log/apache2/

It looks like a circular import. Your generic app is importing from the contacts app, and vice versa. If you are importing to create foreign keys, then refer to the model as a string and remove the imports. See the foreign key docs for more info.
